Another reason you don’t have abs is that you simply don't have the genetics for it. Some people are naturally prone to carry more abdominal fat, and even if they get down to leaner levels with ripped arms and legs, the abs still don't show through. Couple that with the fact that genetics plays a principal role in determining the shape of the abs and the way they look on the body, and you'll realize that if you have genetics working against you, toning your abs is going to be an uphill battle.
